Methadone detoxification is a process which must be supervised by substance abuse professionals within a drug rehab facility who realize how challenging and difficult methadone detox can be. Methadone detoxification is regarded to be far more severe in terms of symptoms and duration than even heroin detox, and users frequently revert back to methadone to relieve withdrawal symptoms or, worse yet, turn to heroin or prescription opioids to relieve symptoms. This is why methadone detox should only be done under strict supervision at a drug treatment center which has experience in handling this type of detox, and where the person can receive additional recovery services to address all addiction issues.
